	Device node - Wikipedia, the free encyclopedia
		Generally, the major number identifies the device driver and the minor number identifies a particular device (possibly out of many) that the driver controls, and is passed to the driver as an argument.
		These device nodes are often used for serial communications devices such as teletype machines, virtual terminals, and serial modems.
		Nodes that lack this correspondence are known as pseudo-devices.

	CHRP ISA Keyboard/Mouse Controller Device Binding
		The value for nodes described by this specification shall be "keyboard" for an ISA keyboard device node, and "mouse" for an ISA mouse device node.
		For devices which are selected as Open Firmware's "console input device" or "console output device" device, the device shall be initialized appropriately for the device to which it is attached.
		For devices selected as Open Firmware's "console input device" or "console output device" device, the state should be unmodified from the initial state on client start-up.

		is an integer that represents the nodes in the cluster.
		Nodes can also have a vote count of zero, for example, when the node is being installed, or when an administrator has placed a node into maintenance state.

	Writing a Device Driver in ChorusOS 4.0
		Device nodes are also used to store specific configuration values as properties, which are made up of name/value pairs and declared in a property file such as my_drvProp.h.
		When the last device entry is released by the last driver client, the shutdown completes and the hardware is put in a clean state for a reboot.
		The development of a device driver is based on the DDI of the class of its parent's driver.

	The USB Serial Driver Layer, Part II
		To create a USB device that works with the generic USB serial driver, all that is needed is two bulk USB endpoints on the device, one IN and one OUT.
		It assigns a USB number to the device and reads the basic USB description from the device, which it then populates into a struct usb_device with a number of struct usb_interfaces that represent the whole USB device.
		After this process, the tty device node is bound to the individual USB serial port.

		But when data is written to a device node, the data is passed to the node's associated driver, and not stored in a filesystem.
		The device driver associated with that node handles enabling and disabling interrupts on the UART, queuing bytes for transmission, and deactivating the UART when transmission is complete.
		But the association between the device node and the device driver is actually controlled via the device's major number and minor number.

	udev
		On device removal, udev queries its database for the name of the device file to be deleted.
		After the device node handling, a list of collected programs specific to this device is executed.
		If more than one device requests an enu- meration for the same name at the same time, it may be possible that both requests receive the same name back from the database.

		The rules for device naming, are read from the files located in the /etc/udev/rules.d/ directory, or at the location specified by the udev_rules value in the /etc/udev/udev.conf file.
		If a device node already exists with the name, the smallest positive decimal integer N is substituted such that the resulting name doesn't match an existing device node.
		The permissions and ownership of the created device file is read from the files located in the /etc/udev/permissions.d/ directory, or at the location specified by the udev_permission value in the /etc/udev/udev.conf file.

		Details about the devices are exported by the kernel to the sysfs filesystem at /sys All device naming policy permission control and event handling is done in userspace.
		If a user has permission to access a specific device node directly and is able to create hard links to this node, he or she can do so to create a copy of the device node.
		If the device node is later recreated with different permissions the hard link can still be used to access the device using the old permissions.

		The ebus bus nexus node is the parent of the child nodes fdthree leaf node (a floppy disk device) and se leaf node (a serial device).
		The ide bus nexus node is the parent of the child nodes dad leaf node (a disk device) and sd leaf node (a CD-ROM device).

	Loop device - Wikipedia, the free encyclopedia
		In Unix-like operating systems, a loop device, loopback device, vnd (vnode disk), or lofi (loopback file interface) is a device node that represents a regular file.
		Loop devices are mostly used for being mounted on a directory, which produces the same effect of mounting a disk whose image is identical to the file associated to the device on that directory.
		The loop device is capable of encryption, the type and strength depend on version of kernel and of util-linux.

	Common threads: Advanced filesystem implementor's guide, Part 4
		Traditionally (without devfs), a kernel-based device driver registers a device with the rest of the system by calling either register_blkdev() or register_chrdev(), depending on whether it is registering a block or character device.
		When the device node (special file) is created, it must sport the exact same major number that is used internally by the kernel.
		In response, devfs_register() adds the foo0 device node to the root of the devfs namespace, and records that this new foo0 node should map to the foo device driver in the kernel.

	Information About Linux Udev Subsystem
		After looking in the udev rules (in the /etc/udev/rules.d/ directory), which specify the device node filename and symlinks, a device node is created in /dev/ with the permissions, which are specified in /etc/udev/permissions.d/.
		udevstart creates all device nodes for the devices, which are compiled in the kernel and for the modules, which are loaded by nash.
		/etc/dev.d/default/pam_console.dev is called whenever a device node is created and calls /sbin/pam_console_setowner with the filename (and an optional symlink) of the device node.

		This includes the device name or any optional device characteristics that are specified in the server configuration file.
		Whenever a device has been added to or removed from the server node, the configuration file must be modified.
		For example, you can find out who uses the device, when and how long it is used, how much data is read and/or written, and number of I/Os to and from the device.

	1394 Node
		A 1394 node is an addressable entity on the 1394 bus.
		A 1394 device is connected to a host controller via 1394 cable, and that device is then enumerated by the 1394 bus driver running on the system where the host controller resides.
		If the 1394 bus driver determines that a 1394 device driver is not controlling real hardware, which again the PDO determines at enumeration time, then the 1394 bus does not automatically fill in the node address for asynchronous requests made by that driver.

		Inter- faces in the libdevid(3LIB) library may be used to manipu- late the handle to the device id. di_driver_name() di_driver_name() returns the name of the driver bound to the node.
		Devices of type DI_PROM_NODEID may have additional properties that are defined by the PROM.

	Removal Relations
		Note that this sort of device node relationship is not the same as a bus driver parent device node/child device node relationship.
		As a consequence of correctly using Removal Relations, Query Remove operations will be applied to all device nodes related to a specific device node through a Removal Relations query, allowing each such device node to allow or deny the remove operations as appropriate.
		Also the assumption is made that a single driver controls both the physical device objects and the virtual device objects in the mux pattern.

		The serial device nodes are provided as a shortcut to assist applications in using the serial ports.
		They are equivalent to opening a port with open(2), and then calling ioctl(2) with the TCGET and TCSET (see termio(7)) commands to set the node behavior.
		The ttyna and ttynA nodes behave identically to the SCO OpenServer nodes.
